| 20110075128 | BIREFRINGENT FIBERS ORIENTATION MEASUREMENT - Methods and apparatus to determine the orientation of randomly arranged birefringent fibers are disclosed. One method comprises emitting light, creating N | 03-31-2011 |
| 20110074946 | Visual appearance measurement method and system for randomly and regularly arranged birefringent fibers - Methods and apparatus to measure visual appearance of birefringent fibers are disclosed. One method comprises emitting light, creating N | 03-31-2011 |
| 20090122322 | INTERFEROMETRIC METHOD AND APPARATUS FOR LINEAR DETECTION OF MOTION FROM A SURFACE - An apparatus and a method for detecting surface motion of an object subject to ultrasound are disclosed. The method comprises generating a laser beam, dividing the laser beam into a reference beam and an object beam to be directed onto the surface, thereby producing a scattered object beam, introducing a frequency shift between the reference beam and the scattered object beam, wherein the frequency shift is smaller than the ultrasonic frequency, detecting the interference between the scattered object beam and the frequency shifted reference beam using a plurality of detecting elements to generate a plurality of electrical interference signals, wherein the electrical interference signals each comprise a wanted signal component indicative of the surface motion and a noise signal component, and processing the electrical interference signals to determine the surface motion of the object. | 05-14-2009 |
| 20090079982 | METHOD AND SYSTEM FOR STOKES POLARIZATION IMAGING - A device and a method for high-speed linear polarization imaging of a scene are disclosed. The device comprises a polarization modulator for modulating the polarization of light emitted from the scene in order to obtain at least three linear polarization states of the light. The polarization modulator comprises a polarizer, a first polarization rotation block comprising a fixed quarter-wave plate and a first liquid crystal operating as a quarter-wave plate, and a second polarization rotation block comprising a second liquid crystal operating as a half-wave plate. Each of the first and second liquid crystals arc switchable between two states, thereby providing the at least three polarization states to the polarization modulator. The device further comprises a sensor adapted to capture image frames of the light from the scene at each polarization state of the polarization modulator. | 03-26-2009 |
| 20090027688 | Multi-channel laser interferometric method and apparatus for detection of ultrasonic motion from a surface - A multi-channel laser interferometric method and apparatus are provided for optically measuring transient motion from a surface ( | 01-29-2009 |
